DRONETRAP TECHNOLOGY

iE's advanced DroneTrap technology captures the pulse waves responsible for the engine's exhaust note and draws them into a mathematically tuned resonator. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones. The remaining waves produce the deepened and enriched exhaust sound you love without annoyance.

EASY SOUND CONTROL

The built-in valve system retains the factory drive select button functionality for easy same-as-stock control. Select comfort to drive around your suburb like a civilized neighbor -or switch into sport mode to open the valves and let it roar!

COMPLETE CATBACK

Our catback design includes all sections to replace the factory exhaust tips, tailpipes, mufflers, resonators, and tailpipes up to the stock or iE downpipe. Enjoy an entirely new exhaust system that delivers the perfect exhaust note from your S3.

QUAD 4" TIPS

Elevate the style of your Audi S3 with the four oversized 4" exhaust tips. The aggressive slash-cut design and sleek brushed finish deliver a distinctive motorsport look bound to turn heads. Depth adjustability allows you to customize the tips to match your unique style—whether you prefer a subtle touch or a bold statement.

ADVANCED ENGINEERING

Advanced 3D scanning tools and cutting-edge software provide our engineers with a high-resolution digital model of the Audi 8V MQB chassis and rear valence. This data is used to maximize the exhaust size for flow and optimize all available space for the perfect catback fitment.

T304L STAINLESS STEEL

A quality catback needs to sound remarkable AND stand the test of time. All piping is constructed of mandrel-bent T304L stainless steel to offer superior corrosion resistance. All joints are hand TIG welded using precise fixtures and tooling. We take great pride in knowing your new exhaust was built strong to last.

STAMPED MUFFLER

The large center-mounted muffler system is wrapped up in our multi-wall suitcase that reinforces the housing inside and out. This level of manufacturing protects the muffler from warping or splitting at the welds under exhaust movement.

REINFORCED HANGERS

Engine movement and exhaust weight are transferred into the exhaust hangers, which puts a lot of stress on the mount brackets. iE's catback system is manufactured with multi-point and boxed-in hanger mounts designed to stand the test of time. Drive confidently, knowing your exhaust is securely mounted and protected against annoying rattles or breaks.

LEAK-FREE CLAMPS

Enjoy a tuned and enjoyable exhaust note without raspy leaks ruining the show. Our exhaust system is assembled with our wide-width stretch clamps designed to seal and pull your exhaust connections together. This style of clamp design is popular in high-end factory applications and is known for long-term reliability.

EASY INSTALL

Install your iE catback without any permanent modifications or installation hassles. The installation process is straightforward and accomplished with standard mechanic tools. An auto-lift is highly recommended.

Install time around 3-4 hours on average
